摘要:
In typical UEs, scanning for WiFi access points (APs) can consume a significant amount of power. This scanning occurs when the UE is connected through the cellular network, but does not occur when the UE is connected to a WiFi network. As a result, offloading a UE from a cellular network to a WiFi network can allow the UE to conserve power. An issue with existing cellular networks is that the UE cannot inform a cellular network that the UE is running low on power, and therefore cannot direct the cellular network to offload the UE for power conservation reasons. A technique discussed herein allows the UE to indicate its power saving needs to the cellular network. In response, the cellular network can lower (or raise) a particular threshold, so that the UE now exceeds (or no longer exceeds) the threshold, and initiates offloading.

Technology is discussed for allowing a wireless mobile device, such as a User Equipment (UE), to coordinate with a Radio Access Network, such as an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN), to tear down a power intensive messaging connection, such as a Radio Resource Control (RRC) connection, to met needs of both the UE and the E-UTRAN. The UE can initiate the tear down process based on information at the UE about the potential need of the UE for the RRC connection and/or the state of the UE's battery charge. The E-UTRAN can then determine whether to grant the request based on the potential overhead involved. The determination can be important to the E-UTRAN because of the large overhead associated with frequent disconnection and re-establishment of the RRC connection. Upon receipt of an affirmative response, the UE can tear down the RRC connection to save battery power.

Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) when mobility is to be supported.

Techniques to control paging for fixed devices are described. An apparatus may comprise a processor circuit, a device identifier component arranged for execution by the processor circuit to determine whether a device is a fixed or mobile device, and a paging component arranged for execution by the processor circuit to generate one or more control directives to modify paging parameters when the device is a fixed device. Other embodiments are described and claimed.
摘要:
Briefly, in accordance with one or more embodiments, a fixed device performs a cell search to search for one or more cells on a network and determines a transmit power level to communicate with one of the cells of the network. The fixed device sets a frequency of updating the transmit power level for communication with a cell on the network, wherein the frequency of updating the transmit power level is reduced for the fixed device with respect to a mobile device.

Techniques are described for a device to request a new service flow for best effort (BE) category traffic to assign a priority to the new service flow. For example, a Traffic Priority parameter in a media access control (MAC) message can be used to transmit the priority level for a new BE category service flow. The MAC message can be an AAI DSA-REQ message (specified in IEEE 802.16m draft 9 (2010)). Either a base station or a mobile station can request a new service flow using the MAC message.
摘要:
Briefly, in accordance with one of more embodiments, a fixed device synchronizes with a downlink channel of a network, acquires a master information block including a last system update time; and executes cell selection without acquiring other system information if the last system update time is before the last system access time. Furthermore, the fixed device may listen only for system information block messages that it needs, and ignore other system information blocks. A bitmap may indicate which system information block messages should be listed to for fixed devices, and which may be ignored. In some embodiments, one or more system information blocks may be designated for fixed devices.

An embodiment of methods and user equipment are disclosed. Once such method includes a user equipment transmitting preferences for Flow-to-RAT mapping to a base station of a network. The user equipment may receive a Flow-to-RAT mapping from the base station that specifies a particular RAT to be associated with a particular Flow.

Embodiments of an enhanced Node B (eNB) and method to provide system information (SI) updates to user equipment (UE) in sleep or idle mode with an extending paging cycle are generally described herein. In some embodiments, a paging message configured to include an optional field to indicate whether there has been a system information (SI) update since a last paging occasion for a UE in sleep or idle mode with an extending paging cycle. System information updates are transmitted by the eNB during a system information modification period that is shorter than a period the extending paging cycle. The optional field may indicate whether or not the UE is to acquire the latest SI update during the current paging occasion.
